See, there's this phone:

Sony Xperia L - GSM Arena


Naka list that there are two variants, the C2104 and C2105. i think C2105 yung binebenta dito, which only supports UMTS 900/2100.

The C2104 supports more frequencies, which i think are in use in the US. Mas advisable bang bilhin yung C2104(UMTS 850 / 1700 / 1900 / 2100) kesa sa C2105? i'm not going to the US anytime soon, but i'm willing to spend a few more bucks to get more frequencies...just in case ;)
